In this article we will see how we can access the batch object of sprite in PYGLET module in python. Pyglet is easy to use but powerful library for developing visually rich GUI applications like games, multimedia, etc. A window is a “heavyweight” object occupying operating system resources. Windows may appear as floating regions or can be set to fill an entire screen (fullscreen). A sprite is an instance of an image displayed on-screen. Multiple sprites can display the same image at different positions on the screen. Sprites can also be scaled larger or smaller, rotated at any angle, and drawn at a fractional opacity. Image is loaded with the help of image module of pyglet. The sprite can be migrated from one batch to another, or removed from its batch (for individual drawing). Note that this can be an expensive operation.

We can create a window and sprite object with the help of commands given below 

# creating a window
window = pyglet.window.Window(width, height, title)

# creating a sprite object
sprite = pyglet.sprite.Sprite(img, x, y)

In order to create window we use batch attribute with sprite object
Syntax : sprite.batch
Argument : It takes no argument
Return : It returns batch object 
 

Below is the implementation  

Python3




# importing pyglet module
import pyglet
import pyglet.window.key as key
    
# width of window
width = 500
    
# height of window
height = 500
    
# caption i.e title of the window
title = "Geeksforgeeks"
    
# creating a window
window = pyglet.window.Window(width, height, title)
    
# text 
text = "Welcome to GeeksforGeeks"
   
# creating label with following properties
# font = cooper
# position = 250, 150
# anchor position = center
label = pyglet.text.Label(text,
                          font_name ='Cooper',
                          font_size = 16,
                          x = 250
                          y = 150,
                          anchor_x ='center'
                          anchor_y ='center')
  
  
# creating a batch
batch = pyglet.graphics.Batch()
  
# loading geeksforgeeks image
image = pyglet.image.load('gfg.png')
  
# creating a list of sprites object
sprites = []
  
# position of images
pos_x = 10
pos_y = 230
  
for i in range(5):
      
    # temporary sprite object
    temp = pyglet.sprite.Sprite(image, pos_x, pos_y, batch = batch)
      
    # append the sprite object to the list
    sprites.append(temp)
      
    # increment the x co-ordinate
    pos_x = pos_x + 100
  
  
# on draw event
@window.event
def on_draw():
        
    # clear the window
    window.clear()
        
    # draw the label
    label.draw()
      
    # draw the batch
    batch.draw()
        
# key press event    
@window.event
def on_key_press(symbol, modifier):
    
    # key "C" get press
    if symbol == key.C:
          
        # printing the message
        print("Key : C is pressed")
          
# image for icon
img = image = pyglet.resource.image("gfg.png")
  
# setting image as icon
window.set_icon(img)
     
     
# getting batch of the first sprite
sprite = sprites[0]
value = sprite.batch
 
# setting this value to the label
label.text = str(value)
 
 
# start running the application
pyglet.app.run()

Output :
